KA20.12

ICD-11 MMS 2026-01

Intrauterine growth restriction associated with small for gestational age

Description

These infants are classified as small for gestational age but have also been subject to intrauterine growth restriction.

Coding note

When both birth weight and gestational age are available, priority of assignment should be given to birth weight.

Coding note from above levels

Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
